For some reason back up for Toshiba laptop appears to have failed during the last 18 months despite having requests for more storage! Virtually no Microsoft files have been saved, which just proves the necessity for having more than one source of back up. Strangely enough our old material has been saved - pre 2013 which is of interest for amateur historains but of little value to someone working from home. On the positive side I have found the Norton Security effective but now question whether their cloud storage is reliable, so don't think that I shall use it for my laptop in future
